Transcribed Image Text: 8. Practically, I would probably be using Python and some graphic software to render an image, but I don't know the type of algorithm (or whatnot) I would need to use to generate the randomized grid. Every cell interacts with its eight neighbours, which are the cells that are directly horizontally, vertically, or diagonally adjacent. The grapes is sold at 235, Create a Python script that will accept three integers and will check each input number. I like using lists because I am comfortable with the syntax that is so similar to arrays in the languages I know, but if there is a better way in Python, I would like to learn it.
